It will be obeerved that upon closing the bridge Z5 by plaeing a conductor between the two teriiiiiials ihereo'il a current will be sent irom the souroe oi power through ihe conductor 23, a. portion ol' the conductor 24, the bridge 2.5, the red light 27, the conductor 28, and the wire back to the Source ol' power. ,if the bridge 25 is open and the bridge 2G closed by' a. conductor, the current will be transmitted through another part oi the wire 24 -V to the bridge 26, to the conductor 30, and

Yfrom that through the w hite lights 31 through the conductors 2Q and 32 back to the source oi power. Iii order to provide for eoiiveniently operating `theee bridges and eloeiiig and opening theii'i at the proper times, i have located theiii :it the iront and rear sid of the easing, as indicated iu the drawings, and i have provided the rover 15 with a pair oi :iiietal plates $53 and 5, adapted to eli-rae. the bridges 'when the Cover is in the 'proper positioii. .'lheSey plaies are sp ei'inetriieted' that w hen 'the cover is ifioeed the plaie iii closes the bridge 2o :iiid throws on ihe white lights and so that when the @over is thrown bi .'libto the position Shown iii.

Having thus desciihed my iiirention, l claini as new and desire to secure h v liet-ters Patent l, A printingv device, c;nnprising; a easingl having electrical conmctifms, two pairs ol resilient plates mounted respectively on the iront and rear ol` theeasing near the top thereof, a cover l'or the casing, said cover haring a plate adapted to engage the rear resilient plates when the cover is open, and i a plate adapted to engage the front resilient plates when the cover is elosed7 whereby' said l effigiati pairs of resilient l resilient plates assist in holding the cover in either closed or open position,

2. A printing devlce7 comprising a easing, a cover therel'or, a palr ol Contact members mounted upon said easing, a pair of Contact members mounted upon said coverJ each oontaet member upoirsaid cover mating a oontactI n'iernher upon said casing, the arrangement heingr such that when said eover is opened .the contact member carried by said cover engages one of said contact mer'nhers mzmnted upon said casing7 and when said cover is closed the other of said contact members mounted uponsaid cover engages the other of said Contactmembers mounted upon said casingy electric lamps of dill'erent colors connected respeetivel)7 with said oontact n'ieinhers upon said casing, and electric connections lroin said lamps to said Contact members upon said easing.
